This invention relates to new and useful improvements in brooder houses for young chickens and has for its primary object to provide, in a manner as hereinafter set forth,

5 a brooder house which embodies a construction and arrangement whereby the walls and top thereof may be rotated in a vertical plane by the wind to prevent the entrance of said wind and rain into the brooder house through 0 the door thereof and through ventilating means which may be provided in the roof Other objects of the invention are to provide a brooder house of the character set forth which will be simple in construction, strong. durable, efficient in its use and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein z- Figure 1 is a perspective view of a brooder house constructed in accordance with this invention.

Figure 2 is a view in perspective showing the stationary supporting frame therefor.

Figure 3 is a vertical sectional View through the brooder house.

Referring to the drawings in detail and to Figure 2 thereof in particular, it will be seen that the reference numeral 1 designates generally a stationary metallic supporting frame comprising the vertical bars 2 arranged in opposed pairs which are connected together at their upper and lower ends by the integral spiders or cross arms 3 and 4, respectively. The spider 3 is provided with a centrally disposed vertical sleeve 5 and the spider i is provided with an opening 6 in vertical alignment with the bore of the sleeve 5. The frame 1 is mounted on supporting blocks 7 secured to the outer end portions ofthe arms of the lower spider 4, and referring to Figure 3 of the drawings, it will be seen that a central supporting block 8 is disposed beneath the connected ends of the arms of the spider 4.

A substantially conical metallic roof 9 is mounted for rotation on theframe 1 through spectively, and disposed in pposed relation,-

to each other. Anti-friction balls 12 are provided in opposed channels formed in the adjacent spaces of therings 10 and 11.

It will be'seen that the ring 10is spaced from the peripheral edge of the-roof 9. Secured to the roof 9adjacent the outer periph cry of the ring 10'and depending from said roof is the cylindrical wall 13 of; the'brooder miner eerie- A liotise'wliicli'extends downwardly closely ad} jacent the vertical bars 2 of-theframe 1 and terminates in opposed relationto the upper side of the supporting blocks 7. The lower end portlon of the cylindricalwall'13' of the;

brooder house rotatably encloses a circular floor 14 which is mounted on the spider 4' between the uprightbars-Z It-may' be here 3 stated that the cylindrical wall" 13 is secured to the roof 9 byfany suitable means such as i the angular clips 15.

At its apex, the roof 9 is provided with an integral upstanding, tubular extension in the form-of a sleeve 16 through which extends '1 the upper end portion of a central disposed verticalrod 17 which extends. through the;

sleeve 5 offthe spider 3 and theiopeningl 6 in the lower spider 4 andis threaded'into the centrally disposed supporting. block's at its lower end. A head; 18 isthreaded on the upper end'of therod'l'? for engagement with the upper end of the extension 16. A wind vane 19 is mounted on one side of the roof 9 and an extension portion 20 thereof extends therefrom to the opposite sideof said roof. Ventilator openings 21 are provided in the roof 9 adjacent the wind vane 19.

As clearly seen in Figures 1 and 3 ofv the drawings, the cylindrical wall 13 is provided in one side and at its lower end with a door or entrance 22. The brooder house is e1evated from the ground by the supporting blocks 7 and 8 and a substantially frustoconical member 23 is, therefore, provided which encircles the lower end of said brooder house and provides means whereby the chickens may climb to the entrance opening 22, as seen in Figure 3. The member 23 may have struck out tongues or projections formed thereon to render the same skid proof.

In operation the vane 19 is engaged by any 5 wind which may be blowing and the roof or top 9 and cylindrical wall 13 will rotate on the stationary frame 1 in a manner to dispose the ventilators 21 and the door opening 22 away from the wind, as will be understood.

It will, therefore, be seen that the wind will be prevented from entering the opening and any rain which may accompany the wind will not enter the brooder house. The rod 17 constitutes means for securing the brooder house in assembled relation and the same may be disassembled expeditiously for the purpos'e'of cleaning the same or for any other reason by simply removingthe threaded head 18 from the rod 17 after which the roof 9 20 and cylindrical wall 13 may be lifted ofi of the stationary supporting frame 1.

It is believed that the many advantages of a brooder house constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall within the scope of the invention as claimed.

'What is claimed is A brooder house of the character described comprising a skeleton frame, a ball race at the upper end of the frame, a second race located above the first race, balls between the races, a conical roof supported by the upper race, a cylindrical wall suspended from said conical roof and extending about said frame, aligned wind vanes on said roof disposed on 40 diametrically opposite sides thereof, one of said vanes being of larger area than the other vane, said roof having ventilating openings therein located adjacent the vane having the largest area, and the wall portion having a door opening therein on the side of the device on which the vane having the largest area is disposed.
